I think tolerance can be understood from the following aspects:
First, know how to be grateful.
Knowing how to be grateful is an ordinary and noble character. Master Xing Yun said, "You must be grateful to enjoy a rich life." . No matter whether our life is in prosperity or adversity and pain, as long as we face it with a grateful heart and have a normal heart that knows how to be content and grateful, whether it is blooming or falling, we can go on calmly and live a wonderful life.
Second, accept your disability.
Life is incomplete everywhere, so learn to accept your imperfect life. When we feel sorry, we can learn to cherish, learn to accept our imperfections, learn to forgive others with ourselves and others, and learn to face an imperfect life with an open mind.
Third, everything is not forced.
There is a saying in Buddhism: Everything is predestined, and life should follow fate. Follow fate, that is, let nature take its course, without sadness, resentment, panic, disorder, impatience, stupidity and importune. So let nature take its course, don't be persistent, be happy with fate, get it with fate, cultivate with the attitude of "joining the WTO" and harvest with the attitude of "being born". This is the highest realm of fate life.
Fourth, look down on gains and losses.
Gains and losses in life are common, and there is no need to entangle them for a long time. Looking down, life will be easy.
